        Release notes for v2.5.7



Summary of changes from v2.5.7-pre2 to v2.5.7
============================================

 (02/02/10 1.248.8.1)
        Remove duplicate CONFIG_SOUND help entries and put one 
        into drivers/sound/Config.help

 (02/03/16 1.522.1.1)
        Link drivers/fc4/fc4.a only once.

 (02/03/16 1.522.1.2)
        Descend into drivers/parport only if CONFIG_PARPORT is set.

 (02/03/16 1.522.1.3)
        Descend into drivers/hotplug only if CONFIG_HOTPLUG_PCI is set.

 (02/03/16 1.522.2.1)
        Fix up ACPI so that it seems to work in the new world order:
        make driverfs initialize early, so that ACPI can come alive
        in a world where you can register devices. 

 (02/03/17 1.525)
        Remove jffs2_sb from struct super_block union.
        Remove FS_REQUIRES_DEV from JFFS2. We never really used the block device anyway.

 (02/03/17 1.524.1.1)
        USB printer update
        
        - bind to 7/1/2 alternate setting by default, to fix printing with HP
          LaserJet 1200 and 2200
        - ioctls needed by the GPL user-mode IEEE 1284.4 driver which is part of
          the HP OfficeJet Linux driver (http://hpoj.sourceforge.net):
          - dynamic switching between 7/1/[123] alternate settings
          - sending HP vendor-specific channel-change-request to support
            memory card readers on HP PhotoSmart printers
          - inquire more information about the peripheral, including
            /proc/bus/usb/xx/yy linkage to get even more information
        - fix apparent array overflow (by 1 entry) in usblp_probe when more than
          the maximum number of USB printers are connected
        - for the 2.2 version, added MODULE_{INC,DEC}_USE_COUNT to prevent rmmoding
          of printer.o (and subsequent OOPSes) while a USB printer device is open
        - cleaned up the code in a few places by consolidating duplicated code

 (02/03/17 1.524.1.2)
        USB Urefs for hid-core/hiddev
        
          I've written a patch Vojtech and I discussed for enhancing the
        hiddev code to optionally provide more detailed output on read().
        The old functionality is still supported by default, and in
        situations where HID usage codes are unique across reports, the
        old method is still preferable due to its terseness.
            
          The new method provides the ability to determine exactly which
        value has changed, in cases where the HID usage codes are not  
        unique.  It also provides a means to optionally receive notification
        when input reports are received from the device, whether or not
        any of the values in the report have changed.
        
          The details of the changes are as follows:
          
          - All current code behaves identically
        
          - A new ioctl pair HIDIOCGFLAG/HIDIOCSFLAG gets and clears
            flags on the hiddev device.                             
        
          - If you set the flag HIDDEV_FLAG_UREF, the read() call switches
            from reading hiddev_event structures to hiddev_usage_ref
            structures.  The change takes effect immediately, even to
            already queued events that haven't been read() yet.  Here's
            an example of enabling FLAG_UREF:                          
        
            {
                int flag = HIDDEV_FLAG_UREF;
                if (ioctl(fd, HIDIOCSFLAG, &flag) != 0) {
                        perror("ioctl");
                        exit(1);
                }
            }
          
          - With the HIDDEV_FLAG_REPORT set (which is only allowed if
            HIDDEV_FLAG_UREF is also set), there is a special uref that
            will be read() in addition to the ones corresponding to
            changes in the device state: when uref.field_index is set to
            HID_FIELD_INDEX_NONE, this uref is a notification that the
            report referred to by report_type and report_id has been
            received from the device.  This can be useful in situations
            when the notification of the arrival of a report is useful
            even if there is no change in state.

 (02/03/17 1.524.1.3)
        USB catc driver
          
        Here is a patch to add support for F5U011 to catc.c driver. The
        patch has been compile tested against 2.5.6 and 2.5.7pre1
        (and tested against 2.5.5-dj1) and should apply cleanly.

 (02/03/17 1.524.1.4)
        USB serial drivers
        
        Several functions in the serial drivers can be called from bottom
        half or interrupt context. They must use the GFP_ATOMIC flag for
        calls to kmalloc() and usb_submit_urb().
          
        Functions which must use GFP_ATOMIC:
        1. All *_callback() functions.
        2. Any code which is inside a spinlock.
        3. write(), throttle(), unthrottle(), which may be called by
           the line discipline in bottom half context.
          
        Functions which can use GFP_KERNEL:
        1. open(), close(), startup(), shutdown(), set_termios().

 (02/03/17 1.524.1.5)
        USB HID driver
          
        Workaround for the ATEN switches

 (02/03/17 1.524.1.6)
        USB printer patch
        
        added NEC printer to quirks list

 (02/03/17 1.526)
        Switch cramfs and zisofs from zlib_fs to common zlib.
        Remove remnants of zlib_fs.

 (02/03/17 1.384.4.15)
        Fix netfilter IPv4 conntrack build.

 (02/03/17 1.384.4.16)
        Make wanpipe build again after struct sock cleanups.
        From Arnaldo Carvalho de Melo.

 (02/03/18 1.524.2.1)
        PPC update - add preempt_count to the ppc thread_info, add
        SI_DETHREAD, plus a couple of minor fixes.

 (02/03/18 1.524.2.2)
        Fix a lockup on some PPC machines running an SMP kernel - we were
        exiting heathrow_modem_enable() with a lock held.

 (02/03/18 1.524.2.4)
        [PATCH] PATCH -- pci_pool and CONFIG_DEBUG_SLAB
        
        I got burnt one too many time by mismatches between
        the pci_pool and "real" slabs... something changed in
        mm/slab.c and broke a driver, so I'm going for the real
        fix this time.  Having poisoning that _works_ is a huge
        help in the innards of the USB host controller drivers.
        
        This patch gets rid of some #ifdefs and makes the pci_pool
        code poison memory if CONFIG_DEBUG_SLAB is set.
        The functionality has always been there, but this makes
        it simpler to get at.

 (02/03/18 1.524.2.5)
        [PATCH] struct super_block cleanup - isofs
        
        Seperates isofs_sb_info from struct super_block.

 (02/03/18 1.524.2.6)
        [PATCH] struct super_block cleanup - udf
        
        Seperates udf_sb_info from struct super_block.

 (02/03/18 1.525.1.3)
        [PATCH] moving stuff to fs/filesystems.c
        
                file_system_typer-related code moved from fs/super.c to
        fs/filesystems.c

 (02/03/18 1.528)
        [PATCH] struct super_block cleanup - shmem
        
        Seperates shmem_sb_info from struct super_block.

 (02/03/18 1.529)
        [PATCH] struct super_block cleanup - hfs
        
        Seperates hfs_sb_info from struct super_block.

 (02/03/18 1.530)
        [PATCH] struct super_block cleanup - affs
        
        Seperates affs_sb_info from struct super_block.

 (02/03/18 1.531)
        [PATCH] driverfs support for ISAPNP driver
        
        This adds initial driverfs support to ISAPNP driver.  It was approved by
        the ISAPNP maintainer (Jaroslav Kysela).

 (02/03/18 1.532)
        [PATCH] for 2.5.7pre2
        
        - add joystick support for CS46xx driver
        - Audigy code updates
        - fix sound/core/Config.in (wrong dep_tristate usage)
        - rawmidi interface fixes (memory leak)
        - chang spinlock to rwlock in pcm_native.c (streams linking)
        - further fixes of dependencies in Makefiles
        - remove experimental time-sync support from sequencer
        - fix/update for 32-bit -> 64-bit ioctl converter code
        - wavefront driver cleanups
        - CMIPCI driver updates
        - update joystick support in CS4281
        - add detection (not support) of M Audio Delta1010LT
        - add AMD768 PCI ID to intel8x0 driver
        - add joystick code to trident driver
        - remove static variable initialization to zero

 (02/03/18 1.533)
        [PATCH] 2.5.7-pre2 IDE 22a
        
        - Apply more patches from Vojtech Pavlik for the handling of host chip setup.
           Hopefully they are settled now.
        
        - Kill unused CONFIG_BLK_DEV_MODES
        
        - Push register addressing down in to task_vlb_sync.
        
        - Make the taskfile parsing stuff actually readable. This is compressing the
           code by an incredible amount. We use just one function doing the whole
           scanning right now. This should make sure that the IRQ handler used by a
           particular command is always right.  I didn't introduce typos hopefully
           here.
        
        - Don't call ide_handler_parser as argument for do_taskfile() any longer. We
           have killed this function by coalescing it's functionality with
           ide_cmd_type_parser() anyway.
        
        - Kill unused SLC90E66 code, which Vojtech apparently missed in his patch.
        
        - sync up with 2.5.7-pre2
        
        Once again the actual patch is rather big mostly due to the removal of
        some default configuration variables which are not used anylonger. So time for
        the next patch stage.

 (02/03/18 1.534)
        [PATCH] Fix linux/msdos_fs.h for userland (1/2)
        
        The following patch moves MSDOS_SB() and MSDOS_I() into #define
        __KERNEL__.

 (02/03/18 1.535)
        [PATCH] cleanup FAT stuff (2/2)
        
        This patch remove unused variable/function/define, and small indent
        cleanup.

 (02/03/18 1.536)
        Include  for completion user

 (02/03/18 1.537)
        Update version

 (02/03/11 1.384.9.1)
        Make USB core init an subsys_initcall, like the other buses.
        
        As it's linked after PCI, usb_init() will be called after pci_init(),
        which is an subsys_initcall, too. Subtle, but right.

 (02/03/11 1.375.25.4)

 (02/03/12 1.388.2.2)
        Increase eepro100 net driver tx/rx ring sizes, to be more appropriate for 100mbit.

 (02/03/12 1.388.2.3)
        Add eepro100 rx soft reset function, for handling RX edge cases the driver
        currently does not handle well, if at all.
        
        Author: Steve Parker @ Sun

 (02/03/12 1.388.2.4)

        reports of hangs or lockups (of the NIC, not the entire system).
        
        Author: Steve Parker @ Sun

 (02/03/12 1.388.2.5)
        Update eepro100 net driver to enable/disable its software timer

 (02/03/12 1.388.2.7)
        Move pci_enable_device and associated code above first PCI resource info access.

 (02/03/12 1.388.2.8)
        Build fix: include linux/crc32.h in bmac net driver.
        
        Noticed by Joshua Uziel.

 (02/03/12 1.420)
        Update defconfig for VLAN and IDE changes

 (02/03/12 1.421)
        [PATCH] 2.5.6 Fix RPC credentials when coalescing NFS reads/writes...
        
          The following fixes up a couple of bugs that resulted from the fix
        in 2.5.4 for ETXTBSY: Since the READ requests now only store RPC
        credentials and not the struct file, we need to be careful when
        deciding to coalesce requests on different pages into 1 RPC call that
        we compare the credentials instead of the struct file.

 (02/03/12 1.422)
        [PATCH] 2.5.6 Fix NFS file creation
        
          The following patch fixes a bug in NFS file creation. Recently (not
        sure exactly when), open_namei() was changed so that it expects
        vfs_create() to always return a fully instantiated dentry for the new
        file.
        
        The following patch ensures this is done in the cases where the RPC
        CREATE call does not return valid attributes/filehandles. This is
        always the case for NFSv2, and can sometimes be the case for v3...

 (02/03/12 1.423)
        [PATCH] 2.5.6 correct NFS client handling of EJUKEBOX error...
        
          The following patch resyncs 2.5.6 with the 2.4.x series w.r.t. the
        handling of the EJUKEBOX error. The latter is an NFS-specific error
        that is returned by servers that support hierarchical storage: it
        notifies the client that the request cannot be completed in a timely
        fashion (Imagine for instance a situation where you have a cdrom
        jukebox system, and the user has just requested a file on another cd).
        
        Under these circumstances, the RFC specifies that the request should
        be retried after suitable timeout during which the server will attempt
        to perform whatever action is required to make the file available
        again.

 (02/03/12 1.388.2.9)
        tg3 gige net driver update:
        * Merge several bug fixes from vger cvs
        * Merge h/w VLAN support, now that API is in the main tree
        * Add support for TX/RX coalescing

 (02/03/12 1.388.2.10)
        8139cp net driver updates:
        * Merge support for hardware vlan accel
        * Better wakeup behavior on TX completion
        * dev->mtu setting fixes

 (02/03/12 1.388.2.11)
        Add several new ethtool commands:
        coalescing, ring params, pause params, hw csum disable/enable,
        scatter-gather enable/disable

 (02/03/12 1.424)
        [PATCH] struct super_block cleanup - ncpfs
        
        Seperates ncp_sb_info from struct super_block.

 (02/03/12 1.425)
        [PATCH] struct super_block cleanup - ext2
        
        Abstract access to ext2_sb_info.

 (02/03/12 1.426)
        [PATCH] struct super_block cleanup - ext2
        
        Complete the ext2 superblock seperation.

 (02/03/12 1.427)
        [PATCH] correction to super_block cleanups
        
        I forgot to zero out the newly allocated memory in the previous patches
        for cramfs and minixfs.

 (02/03/12 1.428)
        [PATCH] correction to super_block cleanups
        
        I forgot to zero out the newly allocated memory in the previous patches
        for ext2 and ncpfs.

 (02/03/12 1.429)
        [PATCH] (1/4) smarter nfs_get_sb()
        
        Switch NFS to use of NFS_SB(sb) instead of sb->u.nfs_sb.s_server

 (02/03/12 1.430)
        [PATCH] (2/4) smarter nfs_get_sb()
        
        Export sget(9), deactivate_super(9) and set_anon_sb(9)

 (02/03/12 1.431)
        [PATCH] (3/4) smarter nfs_get_sb()
        
        Switch NFS to separate allocation of private part of superblock,
        uss explicit sget() instead of get_sb_nodev()

 (02/03/12 1.432)
        [PATCH] (4/4) smarter nfs_get_sb()
        
        Add nfs_compare_super() and teaches nfs_get_sb() to look for existing
        superblocks.

        [PATCH] IDE 21
        
        If I was to give this patch a name it would be:
        
        "Vojtech Pavlik unleashed from the chains".
        
        So credit where credit is due :-).
        
        Anyway here follows the change log:
        
        Mon Mar 11 23:48:28 CET 2002 ide-clean-21
        
        - Swallow rewritten amd74xx host chip setup code from Vojtech Pavlik.  We can
           revert it easly if it turns out to be a bad thing. However the code looks
           quite sane to me. In esp. it doesn't containg that many magic numbers.
        
        - Clean stale white spaces in ide-timing.h tirvial fix.
        
        - Make ide_release_dma return void. It's value is never used anyway.
        
        - Swallow more timing setup code cleanup by Vojtech Pavlik. Apply some
           cosmetics to it. Port opti621 to the new setup code.
        
        - Kill abuse of ide_do_reset() on error return paths for atapi floppy tape and
           cd-rom devices. Just stop them. This gives better changes that defect
           removable media will not cause suddenly broken timings on hard discs
           containing system data! Even then comments in ide_do_reset() admit, that
           resetting the whole channel can have adverse effects on the second interface
           on this channel. And I have too frequently observed linux struggling on
           defect cd-rom for a far too long time to wish it to continue.
        
           Oh did I forget to say that the corresponding "how can I break my system fast
           and reliable" ioctl is gone as well?
        
           Removing it recovered the fact that the CONFIG_BLK_DEV_IDEDMA_TIMEOUT is
           completely bogous. I have removed this option therefore as well, because it's
           playing the same wrack havoc on the devices if enabled. This cat has been in
           an unfinished and *unfunctional* state anyway.
        
        - Actually add physical suspend code to the power handling code.  Still the
           resume code isn't finished just jet. This is all subject to change at the
           point in time when we get to proper command queueing.
           I think however that Pavel will be interrested in tidding this bit up...
        
        - Resync with 2.5.7-pre1.

 (02/03/13 1.436)
        [PATCH] Re: [PATCH] IDE 21
        
        In the FIT macro in ide-timing.h the argument got swapped because of a
        typo. All timings generated for VIA and AMD chips are wrong because of
        that. Safe, though, but slow.
        
        This fixes it.

 (02/03/13 1.439)
        [PATCH] Patch: linux-2.5.7-pre1/net/ipv4/ipmr.c did not compile
        
                It looks like sk->num became inet_sk(sk)->num in 2.5.7-pre1,
        but one of these changes was missed in net/ipv4/ipmr.c.  Here is
        the patch.

 (02/03/13 1.440)
        [PATCH] i82092 PCMCIA driver cleanup
        
        This contains some minor changes to i82092.c PCMCIA driver:
                - MODULE_DEVICE_TABLE() added;
                - request_region() and pci_enable_device() return value checks added;
                - some printk() cleanups.

 (02/03/13 1.441)
        [PATCH] v4l: miro radio update
        
        The updates for the radio driver are all very similar:  The individual
        open functions are gone and replaced by the video_exclusive_open/release
        functions in videodev.c.  All userspace copying in the ioctl function is
        gone because video_generic_ioctl handles this now.  The driver source
        files all become slightly shorter because of this.

 (02/03/13 1.442)
        [PATCH] v4l: usbvideo update
        
        This patch adapts the usbvideo module to the videodev changes.  As with
        all usb drivers, the unplug race fix is present here too.

        This is the update for the typhoon radio driver.

 (02/03/13 1.453)
        [PATCH] v4l: cpia parport/usb update
        
        This patch updates the cpia driver.
        
        Additionally to the usual adoptions to the videodev changes done in all
        drivers this patch has a few more changes:
        
         - some cleanups in the drivers open() function.
         - Use file->private_data to keep a pointer to the drivers private
           data.  This allows to unregister the device unconditionally in
           disconnect(), which in turn fixes some small races in case the
           device is unplugged while in use.

 (02/03/13 1.454)
        [PATCH] v4l: stv usb camera update
        
        This patch adapts the stv usb camera driver to the videodev changes and
        fixes the unplug race.

 (02/03/13 1.455)
        [PATCH] v4l: ov511 usb cam update
        
        This patch adapts the ov511 driver to the videodev changes.  As Mark
        McClelland already sent in a patch with updates this just deletes the
        now obsolete code for the most part.  The unplug-while-in-use race fix
        is also there.

 (02/03/13 1.456)
        [PATCH] v4l: pwc webcam update
        
        This patch adapts the philips webcam driver to the videodev changes.
        Also has the unplug race fix.

 (02/03/13 1.457)
        [PATCH] v4l:
        
        This patch adapts the se401 driver to the videodev changes and fixes the
        unplug race.

 (02/03/13 1.458)
        [PATCH] v4l: quickcam update
        
        This patch updates the parallel port quickcam drivers (bw+color).

 (02/03/13 1.459)
        [PATCH] v4l: saa5249 videotext driver update
        
        This patch updates the saa5249 videotext driver.

 (02/03/13 1.460)
        [PATCH] v4l: vicam usb camera update
        
        This patch updates the vicam usb camera driver.  videodev adaptions are
        there, and the unplug race fix.  I also did plenty of other small
        cleanups and fixes, lots of forgotten breaks in the big ioctl switch for
        example.  I wouldn't be surprised if the driver didn't work at all ...

 (02/03/13 1.461)
        [PATCH] v4l: trust radio update
        
        This is the update for the trust radio driver.

 (02/03/13 1.465)
        [PATCH] snd: btaudio update
        
        This patch updates the btaudio sound driver.  It fixes a bug in the poll
        function, makes the driver a bit more verbose at insmod time, adds a
        insmod option for the pci latency timer and does some minor cleanups.

 (02/03/13 1.466)
        [PATCH] v4l: bttv i2c audio update
        
        This patch updates the i2c audio chip modules.  It improves the support
        for tda9874x chips.  There are some bugfixes.  It also has alot of small
        cleanups: switch some modules to new initialization, declare lots of
        functions static, ...  which make the patch a bit large.

 (02/03/13 1.467)
        [PATCH] v4l: new videobuf helper module
        
        This patch adds a helper module to manage pci dma buffers for video
        frames.  I've recently started writing a driver for another frame
        grabber / TV card chip and tried to separate out common code to avoid
        duplicating code.  The bttv core update (next mail) depends this patch.

 (02/03/13 1.468)
        [PATCH] v4l: bttv tuner update
        
        This patch is a update for the tuner module which controls the tuner
        chip on TV cards.  No major changes, lots of small cleanups: make

 (02/03/13 1.470)
        [PATCH] v4l: major bttv update
        
        This is a major update of the bttv core (0.7.x to 0.8.x).  There are way
        too many changes to list them all, the complete core code for video
        frame capture has been rewritten from scratch.

 (02/03/13 1.384.4.13)
        Integrate NAPI work done by Jamal Hadi Salim,
        Robert Olsson, and Alexey Kuznetsov.  This changeset adds
        the framework and implementation, but drivers need to be
        ported to NAPI in order to take advantage of the new
        facilities.  NAPI is fully backwards compatible, current
        drivers will continue to work as they always have.
        
        NAPI is a way for dealing with high packet load.  It allows
        the driver to disable the RX interrupts on the card and enter
        a polling mode.  Another way to describe NAPI would be as
        implicit mitigation.  Once the device enters this polling
        mode, it will exit back to interrupt based processing when
        the receive packet queue is purged.
        
        A full porting and description document is found at:
        Documentation/networking/NAPI_HOWTO.txt
        and this also makes reference to Usenix papers on the
        web and other such resources available on NAPI.
        
        NAPI has been found to not only increase packet processing
        rates, it also gives greater fairness to the other interfaces
        in the system which are not experiencing high packet load.

        e100 net driver update 3/4:
        - added pci flushing in the e100_set_intr_mask function (pci posting bug)
        - better logic in the prepare_xmit_buff function moving some tx
        buffer initialization code to the start of the function.

        e100 net driver update 4/4:
        - switch to yield function as suggested by you, Arjan and Andrew.
        - fixed broken logic in the use of time_before/time_after - possible
        bug cause in previous design - in most of the places we were going to sleep
        and than check if time expires before checking if condition is satisfied.
        If, for example, we needed to wait up to 3 jiffies we could do
        schedule_timeout(1) and get up after 4 ticks check that time expired and go
        away crying about failure without checking that condition is OK.(in fact I
        saw it happen on one SMP platform here).

        [PATCH] wait4() WIFSTOPPED starvation fix #1/2
        
        This patch (#1) just converts the task_struct to use struct list_head rather
        than direct pointers for maintaining the children list.

 (02/03/15 1.484)
        Cleanup: use list macros for task list

 (02/03/15 1.485)
        [PATCH] wait4() WIFSTOPPED starvation fix #2/2
        
        This patch actually fixes the starvation bug in sys_wait4() by moving any
        process which is serviced for stoppage to the end of the child list.

 (02/03/15 1.486)
        [PATCH] 2.5 and 2.4: fix PCI IO BAR flags
        
        There is a problem where the resource flags sometimes contain bits from
        the address part of the PCI BAR, especially when you have the low address
        bit set for an IO BAR.
        
        (bit 3 of a PCI IO BAR is an address bit, and (bar & 0xf) propagates this
        to res->flags).
        
        This exists in Ivan Kokshaysky PCI patches, and so far hasn't made it into
        the kernel.  It's required for IDE on certain ARM machines to even work.

 (02/03/15 1.487)
        [PATCH] 2.4 and 2.5: remove Alt-Sysrq-L
        
        The following patch removes Alt-Sysrq-L and its associated hack to kill
        of PID1, the init process.  This is a mis-feature.
        
        If PID1 is killed, the kernel immediately enters an infinite loop in the
        depths of do_exit() with interrupts disabled, completely locking the
        machine.  Obviously you can only reach for the reset button or power
        switch after this, leaving you with dirty filesystems.

 (02/03/15 1.488)
        [PATCH] 2.4 and 2.5: fix /proc/kcore
        
        As mentioned on May 11 on LKML, here is a patch to fix /proc/kcore for
        architectures which do not have RAM located at physical address 0.

        [PATCH] fs/libfs.c
        
                Linus, I've taken a bunch of common methods into fs/libfs.c and
        killed the (duplicated) instances in filesystems.  There will be more -
        ideally I'd like to get a library that would make writing small filesystems
        trivial.

 (02/03/15 1.491)
        [PATCH] fix for leaks in nfsd
        
        Several exits in exp_export() forget to call path_release().  Fixed.

 (02/03/15 1.492)
        [PATCH] nfsd as filesystem
        
        * introduces a new filesystem - nfsd.  No, it's not a typo.  It's a small
          tree with fixed topology defined by nfsd and IO on its files does what
          we used to do by hand in nfsctl.c.
        * turns sys_nfsservctl() into a sequence of open()/write()/read()/close()
          It works as it used to - we don't need nfsd to be mounted anywhere, etc.
        * nfsd_linkage ugliness is gone.
        * getfs and getfh demonstrate (rather trivial) example of "descriptor as
          transaction descriptor" behaviour.
        * we are fairly close to the situation when driver-defined filesystems can
          be done with practically zero code overhead.  We are still not there, but
          it's a matter of adding a couple of helpers for populating the tree.
        
                One thing we get immediately is a cleanup of sys_nfsservctl() -
        it got _much_ better.  Moreover, we get an alternative interface that
        uses normal file IO and can be used without magic syscalls.

 (02/03/15 1.493)
        [PATCH] proc_pid_make_inode() fix
        
                In case if proc_pid_make_inode() steps on exiting task we do
        iput() and return NULL.  Unfortunately, in that case inode->i_ino
        doesn't look like inumber of a per-process inode and we take the
        wrong path in proc_delete_inode().  I.e. do dput(PDE(inode)).  Which
        is left uninitialized...
        
                We used to get out with that almost by accident - that code
        worked only because we had zeroed out one field of union and that
        guaranteed that another field would be NULL.  It worked, but broke
        at the first occasion.

 (02/03/15 1.496)
        [PATCH] Cleanup F00F bug code
        
        This changes the F00F bug workaround code to use the fixmap facilities
        instead of touching the page tables directly.  It also removes the
        assumption that only 686's don't have the bug.  I have confirmation that
        the patch works on buggy pentiums. 

 (02/03/15 1.497)
        [PATCH] Fix NR_IRQS when no IO apic
        
        NR_IRQS should be 16 when the IO apic is not configured, as the 8259 PIC
        cannot generate any more interrupts.  It also fixes a bug where the IDT
        gets populated with random addresses, since only 16 entry stubs are
        created.

 (02/03/15 1.503)
        [PATCH] boot_cpu_data corruption on SMP x86
        
        The patch below eliminates a case of boot_cpu_data corruption
        on SMP x86 machines. This was first observed on SMP Athlons,
        but it also affects SMP Intel boxes in a less serious way.
        
        When the secondary processors boot and execute head.S:checkCPUtype,
        the code performs a 32-bit write of a small constant to the
        byte-sized variable boot_cpu_data.x86 (X86 in head.S). Since the
        write is 32-bit, it also writes zeros to the following 3 bytes,
        which clobbers the x86_vendor, x86_model, and x86_mask fields
        previously set up by check_bugs()'s call to identify_cpu().
        Thus, after smp_init(), boot_cpu_data will _always_ identify
        the CPU as an Intel (X86_VENDOR_INTEL == 0 in processor.h) with
        model 0 and stepping 0.
        
        The effect in standard kernels is not catastrophic, since:
        (a) most SMP x86 boxes are Intel
        (b) most uses of x86_vendor occur before smp_init() or reference
            the SMP cpu_data[] array
        (c) most post-boot references to boot_cpu_data occur in the
            cpu_has_XXX macros which only read the x86_capability[] array
        However, third-party extensions (like my x86 performance-monitoring
        conters driver) can get seriously confused by this mis-identification.

        [PATCH] ACPI patch 1/9
        
        This is the first of 9 patches. We did a complete rewrite of the
        Linux-specific code, so we wait for things to stabilize before submitting.
        There will be more updates, but *much* smaller.
        
        #1 - this updates the header file.

 (02/03/15 1.505)
        [PATCH] ACPI patch 2/9
        
        This patch adds in the new drivers.
        
        - Support for driverfs
        - File/code layout more in the Linux style
        - improvements to battery, processor, and thermal support

 (02/03/15 1.506)
        [PATCH] ACPI patch 3/9
        
        This patch updates the acpi IA32 arch-specific files. Part of this is
        taking what was acpitable.c and implementing it with better integration
        with the rest of the ACPI code.

 (02/03/15 1.507)
        [PATCH] ACPI patch 4/9
        
        This is the config.in and makefile changes for the latest code. The most
        (only) interesting thing probably is ACPI is no longer flagged experimental.

 (02/03/15 1.508)
        [PATCH] ACPI patch 5/9
        
        This is the update to the core interpreter code.

 (02/03/15 1.509)
        [PATCH] ACPI patch 6/9
        
        This removes the old OSPM code. It lived under drivers/acpi/ospm/*, but
        the new code just lives in drivers/acpi, and removes some unnecessary
        abstraction that this old code had.

 (02/03/15 1.510)
        [PATCH] ACPI patch 7/9
        
        This updates the Configure.help, both in arch/i386, and in drivers/acpi.

 (02/03/15 1.511)
        [PATCH] ACPI patch 8/9
        
        This patch removes arch/i386/kernel/acpitable.c. As mentioned previously,
        the new ACPI code integrates this, so it's no longer needed.

 (02/03/15 1.512)
        [PATCH] ACPI patch 9/9
        
        If you could only review one of the 9 patches, this would be the one.
        
        - removes acpitable.c vestiges
        - adds ACPI IRQ routing support to PCI (disableable via pci=noacpi option)
        - adds code to get a <1MB page for sleep, and ACPI boot to setup.c
        - allocates another page in the fixmap for ACPI
        - changes driverfs a little to work better with ACPI.

        The appended patch brings the fixes applied in 2.4 to shmem.c to 2.5.
        
        In Detail:
        - Add needed checks for shmem_file_write and shmem_symlink
        - Add Documentation/filesystems/tmpfs.txt and adjust Config.help
        - Add uid and gid mount options

        Fix up ACPI device breakage.
        
        For some reason the ACPI people continue to make the mistake

        them of that notion.

        [PATCH] 1039/1: EXPORT_SYMBOL(dma_spin_lock) for ALSA
        
        Even I do not realy use any ISA code of ALSA on my iPAQ I need it for compilation. As I build ALSA as modules, the dma_spin_lock symbol is missing.
        
        I have seen both definitions of dma_spin_lock (in kernel/dma.c and arch/arm/kernel/dma.c) same as EXPORT_SYMBOL in kernel/ksyms.c, but I think, exporting it in arch/arm/kernel/dma.c should be better then making confusion in kernel/ksyms.c
        
        2Russel: If you don't think this is good solution, we should discuss this in linux-arm-kernel mailing list

        [PATCH] 1036/1: allow APM to be build as module (for 2.5.5) (modified)
        
        This is updated version of patch 1002/1 . As build system in 2.5.5 kernel allows same name of .c files in different directories when computing dependencies and versioning information, the patch becomes simple. Now it just modify appropriate Makefile (in arch/arm/mach-sa1100) and exports one symbol in arch/arm/mach-sa10/pm.c)
        
        This patch replace 1002/1.
        
        (Hope, this is what you want Russel :)

        Re-jig ARMv3 and up page table handing for better correctness with
        Ingo's highmem code.  This also helps with Riel's rmap VM, and
        eliminates the slab overhead for these processors.
